Overview:
  • The safety excess flow check valve is designed to automatically shut off air flow upon a sudden break in the air line, thereby protecting personnel and property from “whipping” air hoses. Allows full unrestricted flow of air while in normal (open) position. Entire unit is corrosion free. It automatically re-sets itself after repair is made. Unit is tamper-proof. Meets OSHA safety regulations
Technical Data:
  • Select the same nominal size safety valve as the hose size leading to the respective air tool. Air flow must be in the direction of the arrow marked on the check valve. A safety check valve should be installed for use before each air tool. The actual length of hose from safety check valve to air tool must not exceed a certain length depending upon the inlet pressure (see chart). The volume of air flow (CFM) through an air line will vary according to its length. A longer line will offer more resistance to flow and thus reduce the volume. The length of a hose extending from the safety valve to the air tool must, therefore, be limited to a certain length to insure sufficient flow to trigger the safety valve in case of a break. Check graph for hose length limitations. The closing flow rate (CFM) at various inlet pressure can be obtained from the flow rate chart.
Caution:
  • Do not reduce safety valve with bushings for use with a smaller air line. If this is done, there will not be a sufficient CFM flow during a line break to shut off the air flow through the safety valve (See Technical Data).
Note:
  • Nominal sizes of valve and connecting hose must be consistent (i.e. 1/4″ valve to be used with 1/4″ hose).
